TYPE-WBITIN G MACHINE.

Application filed December 9, 1912. Serial No. 735,642.

To all whom it may concern:

Be'it known that I, W'nmmn J. NEIDIG,

a citizen of the United States, residing at Madison, in the county of Dane, State of 5 Wisconsin, have invented a certain new and useful Improvement in Type-\Vriting Machines, of which the following is a specification, reference being had therein to the accom panying drawings.

Certain principles and features of my invention as described herein are included avithin the generic invention which is de ,scribed and claimed in my copending application filed April 30, 1908, Serial No. 428,212, on which-Letters Patent No. 1,053,- 919 were granted February 18, 1913.

One of the objects of my general invention is to indicate to the operator of a typewvriting machine the distance from the current printing point to one of the ends of the sheet, or to another point on the sheet, and this progressively, and without preliminary care on his part.

An additional object is to supply the operator with one or another type of indicating means whereby a signal is given in an improved manner at a predetermined sheet position.

The present embodiment of my invention is distinguished by various novel features, among them the use of novel electrically controlled indices; the use of glow-lamps to indieate progressive sheet-positions in various novel ways; the use of a paper-feeler o'l' novel construction and having novel actuation both into and out of the paper-path, the use of a novel slant-fated stop, and also of novel means for actuating the saline: and the use of certain no-vcl combinations of ele i meuts adapted to render the invention more useful in practice.

In the accompanying drawings,-l igure "1 is a vicvv from the end of a portion of a tvpmvriter carriage having my device thcreon, and of my electrical indicator, here given -vertical position for clearer illustration, with certain portions of the structure broken away. Fig. 2 is a view from the front of portions of the same. partly in section. Fig. is a view in section on the line Fig. 1, of certain portions of the mechanism shown in Figs. 1 and 3. Figs. l and 5 are diagrammatical re n'osentations of addi- Specification of Letters Patent.

device. Fig. 6 is a detail view of stop 15. Fig. 7 is a detail view, partly in section, of the paper-feeler. Fig. 8 is an end View, partly in section, of a modification of the portions of the mechanism for actuating the papenfeeler and stop.

Referring to the dra\vings,-I show only such typewriter parts as are necessary to a full explanation of my invention, certain parts not shown being such as are in conamon use and Well known in the art and not requiring detailed description, as will be understood. At 47 is indicated one end of the shifting platen frame on the usual latorally moving carriage of the machine, in which is journaled platen arbor l3 bearin platen 10, the same beingfixedly attached upon the said arbor by means of platen head 39 in usual manner. The platen as consiob cred herein is the principal feed-roll for advanciug the sheet; and it is rotated by usuai linespace mechanism oi any approved type. The usual twirler 50 fOIXJ IIdIEPQHdBIIlS rotation of the platen is shown. At 8 is the usual paper-table for the support of the entering sheet.

The embodiment of my invention shown in the drawings comprises an operative mom her journaled on platen arbor 13 so as to revolve thereon irulependcntly ol the platen. Said member '3 is in form a drum or indexcarrier. having (Fig. 3) a rim portion, an upstanding portion. and a hub or bushing portion. Rotating loosely within the contour thereof is a driving element 11, the same being fixedly attached upon platen head 39 to revolve therewith. W'ithin the contour of part 11 is friction-ring I. preferal'ly constructed of resilient material, and having a tendency to expand radially into frictional contact \vithpart 11 so as to be driven thereby said parts 1] and T constituting the driving and driven elements respectively of a convenient form of clutch uujchanism. Said ring 7 bears adetcnt or pin i-l, preferably -near one end as shown. This pin projects outwardly through a short radial slot 5 (Fig. 3) in the upstanding portion of drum (3, thus coupling: ring 7 d drum =3 together so that said drum niusi volve with ring 7. v

rame 17 bears an inwardly projecting pin or axle 20. journalcd upon which is tional indicesflulatcs to be supplied with my sleevr 21. Fixedly attached upon said sleeve segment a tendency to revolve with said in suit-allle lateral positions are toothed seg P ment 15, stop 15, and paper-feeler butt '28. Segment it) engages with toothed segment 14, which is supplied with a split hub 111, on arbor 13. Clamp-bolt 9 and its lock-nuts and compression spring 7 serve to tighten said hub lll upon arbor 13 into frictional engagement therewith, thereby giving said arbor.

A washer may he used against frame ll to hold huh 111 in advantageous lateral po Sition. Stop 15 has at times ajposition in the path of pin 14 and cooperates therewith as one of the dctent elements to detain drum 6. The fare of the stop is preferably slightly slanted heel; on line 1:3 away from are 15- thereof (Fig. 6), and supplied with flanking safety guides 15. That is to say, it is 'iven'a am contour, so that it will retreat l rom pin 14 during withdrawal. The fact that the stop is a cam segment, or slantfaced, facilitates its disengagement from pin 14. The paper-feels! employed is knucklejointecl (see Fig. 7) md consists of a butt portion 28' and a paper-eontaeting or tip portion 28, one thereof journaled on the other by means of a pin 23. The hull: portion recessed to reeeive the tip portion, and a lug portion 28 of said tip porti n bears against the butt, thereby limiting the action of lllC tip on the butt, and holding the parts so that a straight line drawn through the prin ipal eeler-axis at 20 and. the paper controlled feelertip will pass slightly to the paper side of the axis at :23 and a straight line drawn through said axes 20 and 23 w ill intersect the first line at an angle. A knuckle-feeler so constructed may conveniently he termed angle-iointed. lts purpose is to insure disengagement of the feeler-tip with the sheet in backing-up, backward pre+ sure againsttthe feeler-tip tending to knuckle the l'eeler away from the sheet imlrpemlentl of an other retracting force. Paper table 8 has a short opening or slot :1 therein. into nhich the papert'eeler has its path for a limited distance, the end of the hlol. eonstiruling a stop to prevent the exces; 've move ment of the feeler into thepapenpath. An inwardly projecting pin on frame t7 has attached thereto the shield-pointer 3 t to reoperate with drum 6.

The 'tion oi the mechanism thus far do smiled is as hillowsz Plnlen twirler is gi en e l'frht backward actuation, thereby through arbor l3, split huh 111 and segments ll and 5, rocking sleeve ll and moving the paper-teeler into retracted position against the platen. The sheet is then enliercd into the machine, as usual, and the platen rotated to feed it forwardly. There upon segment 14', frietionally actuated from the platen arbor, acts upon segment 15',

IHI'l-IS sleeve 21, and through it brings paperfeeler against the sheet over slot 1. This action hrings stop 1?? into the path of pro jertion I; on drum 6. ,\s the sheet is further llllViIlCtfll in printing, drum ll, frirtionally ruinnected with the platen througg h l'rirtioiu ring 7, revolves. until projwlion 14 is stopped by slop 15, as shown in Figs. 1. and The pressure of stop 15 upon projection ll seated as shown in the end of the frielltilhllllg 7 stops said ring and connected drum. and at the same time totals to open the frictional surface and lessen the friction. in this position the parts will remain until the end of the sheet passes papenl'eeler The instam the end ol the sheet clears the paperleeler. the leclcr, no longer detained by the sheet, and actuated by part 14', passes into slot 4, sleeve 21 is rocked, and slop 15 is withdrawn than the path of projection 14 in a positive action proportionate to the speed with which the machine is operated, releasing drum 6, which at once takes up its movement with the laten. In ease of hackward actuation of t e platen at any time in the progress of the sheet, stop 15 is retracted ,frrm the path of projection Li and the paper-feeler is retracted from sheet-controlled position, thereby permitting projection ll to he backed past stop l5 and the sheet to be fed hacliwarrlly Without interference from the paperateeler, the retraction being accomplished under the actuation of part 14' on the platen arhor.

Through this drum or operative member 11 indieating m ans of the tolle'm'ing nature are called into operation: First. I place on the feripherp ol the drum indiees for in dir-ating the shee'lf position. Since drum 6, outrollial as it is by the sheet. must brine always the salnc point on its periphery up posite poih ter Ell when the end of the sheet attains any given distancifrom the priutirng point, I supyjwly the drum will. indire-s. using any unit of nu-ann'emtmt de ired. in that the, distaiiee from the printing point to the end ol? the sheet, or to a point on the sheet a dclinite distance lherel'rou'l. will he indicated from the time prperi'ceh-r 229 is relcaeml l]\' the sheet until the sheet leaves the machine. In the drawings the indiration is hy liuc units. I prefer to use upon this drum or indrirrarrier indiees involving no mental r: l culation nor memorizing on the part of the operator. ll is to he noted that the indicatingrllI'fflCG upon index-carrier (5 is divided into two segments. only one of which preferably rolored black, is visible to the operator {luring the detention of the rarrier, the

nth that having the indiees thereon and.

pret'erahly colored white lying eoncealed hehind Hlllijlt'l]]()l!lt ?l ill in this position of the carrier. When carrier 6 begins its indicating functions the black segment disappears and the white segment bearing the iudices takes its place, the mere change 111 color servrespect to member 6, its driving mechanisin, and the several types of indicating means called into operation through Inemher 6. Segments ll and 15 are however not employed. Frame 47 has journaled therein the inwardly extending rock-shaft 20. Said rock-shaft on the outer side of said frame bears the fixedlyattached lever and inwardly of said frame the stop 1o 15 and feeler-butt 28 are fixedly attached as before described inconnection with Figs. 1 and '3, both stop and paper-feeler having the same construction as before. Instead of the usual laten-twirler, a twirler 50 15 loosely jonrna ed on the platen arbor is used, having an inwardly extending bushing or sleeve-portion 52 and radially outward thereof an inwardly extending sleeve portion with a space between the two for the reception of a. contracting spring 51.. Sleeve portion of said twirler has a short slot 55 therein, underneath which is -a hole 50" adapted to receive the bent-in 'end of spring 51. A bent-out end of said 5 spring'passes throu'gh a hole in sleeve portion 51- of the twirler. The twirler is thus held in operative position laterally on the platen-arbor by the spring-ends, and has a limited rotative movement opposite to 30 line-spncc direction against the action of the spring. Fixedly attached upon said twirler is pulley 15 A light cord or belt 111* encircles the pulley. the ends of which are attached to either arni of lever 13 in such manner that when the pulley is actu-- atcd in line-space direction shaft 21') is rocked to press 'paper-feeler 28 toward the paper-path, and when actuated in opposite direction paper-fceler 28 is retracted toward 40 the platen. Said belt is adapted to slip frictionally upon said pulley, the engagem'ent therewith being only suflicient to actuate rock-shaft 30' and its parts. Spring 51 is sufficiently strong, to actuate said pul ley against the friction of the belt. but is not strong enough to rotate the platen. In all other respects the mechanism is as has bccn hcrciubci'orc dcscrihlul.

The action of the modification is as follows: In the event of backward actuation of thc platcn through the-platen twirlcr. as in practice. twirlcr 50 and pulley 1f, are otated a short distance against the action of spring Bl bctore the end ol slot s5 5:) meets the bent-in portion of the sa d spring: and theplaten is rotatedaconsequrntly p:u 'icr-r'celer 523 under the action of pullm' 13 hclt 111. lever 15*; and rocln shaft 20'. is or may be quite retracted from shoot-controllcd position before the short begins to more backwardly. Stop 15 like nise is or may be quite retracted from the path of projection 14 before said. projection begins to more backwardly. Forward actuation of the platen through the action of the platen arbor, twirlert) spring 51,

puller i3", belt 111 lever 15 and rockshaft il causes the paper-feeler to be actuated toward the sheet and the stop to be aimed into dctaiuing position in the path of brojcctioii ll. In all other rcspccts the action is the same as has been described in connection with the earlier figures.
